They work in all departments for classical music.
I've found a tube pre-amp to be a very good fit however I looked specifically for an ICEPower based amp that implemented higher input impedance than stock ICEPower modules which are 10K ohms I believe in order to minimize distortion which can wreck havoc on classical music in particular.
The Bel Canto Ref 1000 mkiis are 100K input impedance unbalanced. Older less expensive BC Ref 1000s (not mkii) are stock 10K input impedance as is the S300 I believe.
Wyred4Sound amps are ~60K ohm input impedance.
There are others as well, but many vendors of IcePower amps go with the stock Icepower unit and basic configuration. That may not be a good match on paper with some tube pre-amps having higher output impedances.
